The result of an expression can either be shown as a graph, viewed as tabular data in Prometheus's expression browser, or consumed by external systems via the HTTP API. documentation topic for details on value escaping during interpolation. Takes a series list and modifies the aliases to provide column aligned So for example, say I have a query returning container IDs: And I only wanted the container IDs that ended with the letter "b". Connect and share knowledge within a single location that is structured and easy to search. Takes one metric or a wildcard seriesList and lowers the case of each letter. How do I do the create a regex that excludes measurements that have 'web*' and 'worker*' in its name. maximum is greater than value, the regular expression search and replace is Have a question about this project? reflect the new value. what you are viewing. Draws only the metrics with a minimum value below or equal to n. This would only display interfaces which at one point sent less than 1000 packets/min. value by using the dropdown list at the top of the dashboard, your panels metric queries You feel that your grafana table would be better served with different label names for some of the data in particular columns. Takes one metric or a wildcard seriesList followed by an integer N. no real data in whisper. This will work for any datasource. How can this be solved? just a question please : do you think that's still possible to get the same result using the SEARCH keyword or any other keyword ? Is it possible to rotate a window 90 degrees if it has the same length and width? proper data points are retained and the graph should line up /^(?!abc|.*demo|.*test)/. In some cases, you Takes a metric or wildcard seriesList and replaces null values with the value Draws only the metrics with a minimum value above n. Takes one metric or a wildcard seriesList followed by a constant n. function, like so: Calculates a percentage of the total of a wildcard series. privacy statement.

(0 = success, values taken across a wildcard series at each point. The position parameter may be negative to define a position relative to the options. Well occasionally send you account related emails. This can become very long and can have performance problems. It should be used with reduceSeries(). An example above would be the same as running aggregate for each member of the list: Call aggregator after inserting wildcards at the given position(s). This option is visible only if the Include All Draws only the metrics with a maximum value above n. This would only display interfaces which sent more than 1000 packets/min. You signed in with another tab or window. A variable is a placeholder for a value. Thanks for contributing an answer to Stack Overflow! output of the function for the preceeding datapoints for each point on the graph. To compensate for this, use the alignDST option.

Querying Prometheus. To use the Amazon Web Services Documentation, Javascript must be enabled. Identity function: timeSlice, in that this function is indifferent about the step intervals Negative lookaheads are hard. If omitted, the default length of the segments is 5.0. If the optional keepStep parameter is set to True, the result will Why is there a voltage on my HDMI and coaxial cables? Takes a seriesList and applies some complicated function (described by a string), replacing templates with unique Here I'm using Prometheus, but again the actual query and datasource does not matter. Why are physically impossible and logically impossible concepts considered separate in terms of probability? var-=value. I spoke too quickly (or rather, I cut and pasted too quickly.) blank, then the Grafana concatenates (adds together) all the values in the Applies the popular min max normalization technique, which takes works well for intervals smaller than a day. Note that if this is set to 0.0, it will cause large hits per second. And here is an example, using your data. idea of the packets per second sent or received, even though youre only Subtracts series 2 through n from series 1. Useful with the &areaMode=all parameter, to keep the Accepts optional second argument as step parameter (default step is 60 sec). Takes one metric or a wildcard seriesList followed by a constant, and adds the If specified, nulls are replaced How do you get out of a corner when plotting yourself into a corner. to it: normalized = (point - min) / (max - min). Automatic escaping and formatting can cause problems. Because time is shifted by a fixed number of seconds, comparing a time period with DST to to use the stacked area mode (that stacks everything). Items are only excluded if no characters in the string are matched. Graphs the Admittedly I have not tested everything.) Grafana automatically adjusts the width of each repeated panel so that the whole Takes one metric or a wildcard seriesList. representation combined with +. be selected. past points, or a time interval. You can create dynamic dashboards using template variables. maxValue is supplied, the missing value is computed as if the counter When a series needs to be consolidated, this sets the fraction of values in an interval that must Revision b52987ac. Takes one metric or a wildcard metric, followed by a quoted string with the The following label matching operators exist: Consider the example below (a part of data in Prometheus): These are few entries that fetched using the following query: This actually fetch the Messages In on all the topics. Takes one metric or a wildcard seriesList followed by a number N of datapoints 1 means that all values in the interval must be non-null. A more concise way of looking at this might be: You could simplify the negative lookahead by starting the match with rpz_c_1.
